USS Chicago (NCC-75011) was a Sovereign-class heavy cruiser in service during at least the 2380s. (Starfleet International: USS Chicago) Many of Chicago's senior staff trained aboard USS Bortas. In 2384, Chicago — whose commanding officer was Captain Jay Hurd and whose executive officer was Commander Stephen Whyat — was deployed to the Starfleet Twelfth Fleet. Captain Hurd, formerly Gul Ja’Hurd of the Cardassian Union, defected to the Federation out of growing disagreement with the Union’s policies. Tyronian, a Bajoran, volunteered to serve as Ja’hurd’s XO, not so much to for the position, rather, to keep an eye on the Cardassian. Ja’Hurd’s wife, Amaree, was assigned to serve as the ship’s Intelligence Officer. Rumors persist that Ja’hurd and Amaree both may be cover identities themselves,
